GEOTETTPES. 113 



The other characters mentioned by Jekel — the blue colour, the interrupted basal margin 

 of the thorax, and the deeper and broader elytral strise — are found in indubitable 

 examples of G. fronticornis. 



3. Geotrupes mniszechl. (Tab. VII. figg. 13, 6 ; 13 a, side view of head and 

 thorax. ) 



Geotrupes (Ceratotrupes) mniszechl, Jekel, Ann. Soc. Ent. Er. 1865, p. 544 \ 



3 major? Capitis cornu quam in G. fronticorni, sed multo longiore, antice oblique porrecto apice recurvo, supra 

 sulcato ruguloso-punctulato. Thoracis cornu multo angustior et longior, apice sat profunde fissum. 

 Corpus breviter quadrato-ovatum, cyaneum. 



Hab. Mexico 1 (Salle). One example. 



From the description given by Jekel of the general form 1 (taken from a single 

 example, a 6 minor from the Mniszech collection), the shape of the thoracic protuber- 

 ance, and the outline of the thorax, I think there is good reason to conclude that 

 the specimen above described belongs to the same species, which is thoroughly distinct 

 from G. fronticornis. 



4. Geotrupes sallaei. (Tab. VII. fig. 14, s .) 



Geotrupes (Cnemotrupes) sallei, Jekel, Ann. Soc. Ent. Er. 1865, p. 596 \ 

 Geotrupes (Cnemotrupes) sallei, VEiV.falsus, Jekel, loc. cit. p. 598. 



Hab. Mexico, Oaxaca l , Duraznal (Salle). 



On examining the type of G. falsus, kindly lent by Dr. Sharp (the possessor of the 

 Saundersian collection of Lamellicornia), I find it to differ from the few examples we 

 have of G. sallcei exactly as stated byM. Jekel; but the differences are evidently only 

 individual, and the specimen is doubtless from Mexico, and not from Peru, as 

 labelled. 



5. Geotrupes viridi-obscurus. 



Geotrupes (Cnemotrupes) viridi-obscurus, Jekel, Ann. Soc. Ent. Er. 1865, p. 599 l . 

 Geotrupes (Cnemotrupes) saundersii, Jekel, loc. cit. p. 598 2 . 



Hob. Mexico, Orizaba, Parada, Duraznal (Salle), Oaxaca (Salle, Edge), Salazar 

 (Edge), Mochitlan (Baron). 



M. Jekel was right in doubting 2 that the specimen on which he founded his 

 G. saundersii came from Peru. It is a female differing in nothing but trifling indi- 

 vidual peculiarities from Mexican specimens of G. viridi-obscurus of the same sex. 

 The chief difference adduced by the describer, viz. the fuliginous antennal club, is due 

 simply to a coating of dirt on that organ. Dr. Sharp informs me that there are other 

 instances of specimens inadvertently labelled Peru instead of Mexico in the Saundersian 

 collection.
